Shearing type intelligent weeding robot based on weed prescription map

Abstract

The invention relates to the field of agricultural machinery, and discloses a shearing type intelligent weeding robot based on a weed prescription map. The weeding robot is composed of a connecting frame, a parallel mechanism and a weeding mechanism. The device is installed on a walking platform through the connecting frame, movement of het parallel mechanism is controlled through obtained weed position information, the weeding mechanism is moved to a weeding area, accurate positioning work in different environments is achieved, then the device cuts in from the side face through adjustment and selection of the weeding mechanism, accurate shoveling is conducted, the operation efficiency and the working quality are greatly improved, the robot travels in the field along with a vehicle-mounted platform during working, a servo motor is controlled to move according to the position information of weeds, the parallel mechanism is controlled to move, a shear knife of an end executor and a clamping device achieve shearing movement under the movement of an air cylinder, roots of the weeds are cut off and chopped, stems and leaves of the weeds are moved out of soil, regeneration is avoided, and the weeding effect is good.

Description

technical field [0001] The invention discloses a cutting-type intelligent weeding robot based on a weed prescription map, relates to the field of agricultural machinery, and is specifically applied to the intelligent weeding of various crops in the agricultural field. Background technique [0002] Weeds and crops will compete for growth resources during the production process, resulting in reduced yields, so weeding has become the most important link in agricultural production. The development of weeding technology is very rapid, and the weeding methods are naturally varied. At present, in terms of weeding, we use more mechanical weeding and chemical weeding. The effect of chemical weeding is good and the cost is low, but the excessive and improper use of chemical weeding has obvious disadvantages. First of all, improper use of chemical herbicides can lead to phytotoxicity, damage or even kill seedlings, and pollute the environment. Second, poor control of herbicide dosag...

Problems solved by technology

There are usually two most direct methods of mechanical weeding between plants: 1. Cutting off the roots or stems of weeds 2. Uprooting weeds. Both methods can effectively remove weeds, and the second method is more effective in removing roots." The first method of weeding is to retain some factors that are more beneficial to the plant when the effective weeding effect is achieved, but the two mechanical weeding methods eliminate the chemical weeding while ensuring the weeding effect and weeding efficiency.
